CRYSTALLOGRAPHY AND NEUTRONS
| - |
In Oléron
On the occasion of the International Year of Crystallography, the French National Neutron Society is organizing an international school on "CRYSTALLOGRAPHY AND NEUTRONS" which will be held in Oléron (France) from 21 to 24th September 2014. There is still time to register (deadline: June 30).
This school suits beginners and advanced researchers wishing to explore and use the capabilities of neutron scattering. The courses will be taught in English.
For European (non-French) students, NMI3 can support the participation of students preparing a formation in a Non-French European University in the frame of "Neutron and Muon European Schools" (NaMES).
The school will focus on the specific strengths of neutron scattering (magnetism, light elements, contrast methods) and present the most relevant neutron techniques for various materials, their limitations and their application fields. It will also show the main technical characteristics of neutron scattering spectrometers available to the French and European communities of crystallographers, chemists, physicists and specialists of Materials Science.
The training will take place over 4 days, during which lectures on the different techniques of neutron scattering will be provided together with practicals. Specificity and complementarity of these techniques with other laboratory techniques (diffraction and X-ray scattering, reflectivity, X-ray spectroscopy and Raman inelastic scattering) will be highlighted.
Fan du LLB school
| - |
In Saclay
Fan du LLB is an annual school delivered in French and offering young French-speaking researchers a first contact with real experimental neutron scattering. The school is aimed at students and post-docs working in all scientific areas where neutrons can provide valuable insights, although priority is given to those having never had any contact with neutrons scattering.
After an introduction to neutron sources and neutron scattering, ten different thematic subjects based on different scientific problems that can be addressed by neutron scattering, are proposed to the students. In groups of four to five, the students are then introduced to two different neutrons scattering technique, during three days devoted to experiments and data analysis. One of the distinguishing features of our school is that the students often come with their own samples, which are tested during the training together with our demonstration samples. This ensures a good and efficient participation of the students. The course lasts for 3.5 days.
Neutron Scattering. Gordon Research Conference
| - |
In Hong Kong
Effect of Disorder and Disordered Materials
This new Gordon Research Conference (GRC) on Neutron Scattering, to be held in Hong Kong in 2015, will feature world-leading neutron scattering scientists who will share and discuss their latest discoveries in the GRC (interactive) style. As it is impossible to capture all new activities over a very diverse field of neutron scattering studies, the conference will instead focus on selected topics that have seen rapid developments over the last few years. Innovative instrumentation is the backbone of scientific discoveries, and thus one of the nine sessions will be devoted to discussions of the performance of innovative instruments. A diverse and vibrant user community is vital for the success of the neutron scattering facilities. We thus particularly encourage the participation of young scientists, to learn and profit from interactions with leading scientists in neutron scattering in the casual environment provided by the conference.

ESS Science Symposium: "Surface and Interface Reconstruction: A Challenge for Neutron Reflectometry"
| - |
In Munich
Today, a large variety of complementary analytical techniques are routinely employed to determine and analyze surface structures and interfaces in situ. Electron microscopy, AFM/MFM, STM, LEED, photo electron spectroscopy, ellipsometry as well as classical x-ray and neutron diffraction/reflectometry and grazing incidence surface scattering give a wealth of information from the Ã...ngström to the micrometer length scale. However, classically, electron or ion based surface science techniques are limited to the vacuum environment. To determine structural or magnetic parameters of surfaces in ambient environmental conditions, like a surface submerged in a liquid, surface x-ray diffraction (SXRD) is used. Likewise, to access buried interfacial or magnetic properties within a heterostructure of layers, reflectometry with polarized neutrons has proven to be a very powerful tool, which allows a non-destructive depth profile vector magnetometry, to be carried out.
Structural in situ characterization of heteroepitaxial growth with x-rays can be used to track details and quantify parameters generally inaccessible to other non-destructive methods applied during growth. A variety of instrumental developments allow for optimum growth conditions during x-ray scattering experiments and for an in-depth analysis of the complete epitaxial process showing the different growth phases and a quantification of a variety of parameters involved in such processes. Coherent x-ray diffraction is capable to provide not only the structure but also dynamic information on atomic monolayer deposition on surfaces.
More recent developments allow the magnetic characterization during thin film growth to be carried out using magnetic x-ray scattering techniques. Further, currently the experimental capabilities for polarized neutron reflectometry during thin film growth are being developed to allow the understanding of the evolution of magnetic domains and the movement of domain walls in the nanometer regime.
In the past, neutrons have been applied to study surface and interface structures mainly using specular neutron reflectometry, which is an established method today and available at all major neutron sources world-wide. Within the last decade also off-specular neutron reflectometry and grazing incidence small angle neutron scattering (GISANS), either monochromatic or using time-of-flight, have moved into the focus of interest with significant developments in measurement techniques and data analysis. These methods are hence very powerful for the determination of structured surfaces in the Ã...ngström to micrometer length scale (see the ESS Workshop on Off-Specular neutron Scattering, Brussels 2012).Â
Nevertheless, grazing incidence surface diffraction with neutrons is still often unknown to the potential user base, mainly due to the general understanding that due to the low available neutron flux and the large sample sizes required, these experiments would be rendered impossible. Some unique properties of neutron scattering like the isotopic conÂtrast variation to label specific molecular structures or atoms in e.g. soft matter systems are hence unexploited.
Undoubtedly, the current trend in research with neutrons is to decrease the sample sizes. Therefore, it is very important to adapt the experimental techniques to cope with small scattering cross sections and little sample material. Higher flux neutron instruments and focusing on small sample areas are, hence, the pre-requisite to enter this field of research. The option for more intense neutron beams at new spallation neutron sources (SNS, J-PARC, ESS) and the development of novel neutron optical concepts open completely new and challenging possiÂbiÂlities for the structural analysis of surfaces and interfaces with the vision to perform structural and magnetic surface reconstruction by neutron scattering.

The Future of Dynamic Structural Science
| - |
In Erice
Purpose of the Course
The determination of three dimensional structures of new materials is frequently the starting point for mechanistic studies, revealing structure-property relationships, modelling of molecular variants and intelligent design for specific properties. However, these are traditionally static results and although we can follow structure evolution with temperature and pressure, it is far less easy to study time evolution when the time scales of the processes involved are short. The latest high intensity X-ray sources, fast detectors, new techniques and modern software are now taking us into the regime of conducting timeâ€"resolved studies and it is this aspect of structural science that we shall be exploring during this course.
X-ray and neutron diffraction are the most powerful methods for elucidating full 3-D structures from single crystals and microcrystalline powder samples for many forms of matter. The techniques are continuously evolving enabling ever more challenging questions to be addressed and the most difficult of problems to be solved. We shall be describing time resolved studies in crystallography, spectroscopy and computation and looking also at applications of this work as well as looking forward to the future and exciting opportunities and challenges that facilities such as XFEL will bring to the field.
We shall concentrate during the course on:
1) Photocrystallography â€" obtaining structural information from short lived crystalline species.
2) Time resolved spectroscopy - identifying and characterising intermediates and correlating these results with structural data.
3) The future â€" current and upcoming developments in dynamic structural techniques.
4) Theoretical calculation â€" correlating with and supporting experimental studies through computational calculations.
And in addition to the lectures we shall be presenting demonstration and workshop sessions providing training in using modern computer programs in these aforementioned areas.
International Conference on Neutron and X-ray Scattering 2009

In Kuala Lumpur
International Conference on Neutron and X-Ray Scattering (ICNX 2009)
In view ofthe success of previous neutron and x-ray scattering conference in this region (ICNX 2007, Serpong and Bandung, Indonesia), it has been decided to reconvene the International Conference on Neutron and X-Ray Scattering, in 2009. The conference will take place from June 29, 30 and july 1, 2009 at Putra World Trade Centrre, Kuala Lumpur, Malaysia.Â
Scattering technique using neutron and x-ray is a powerful method to probe and study the structures and dynamics of materials ranging from the mechanics of protein folding and its effect in physiology to the ordering of atomic magnets of solid materials of industrial interest. Both neutron and x-ray can be exploited using a variety of measurement techniques to provide information not otherwise available.Â
The availability of new optical system that can micro-focus neutron provides opportunity to explore new characterization technique and full-utilization of small research reactor that scattered throughout the world. The emergences of new synchrotrons allow more scientists to use high-intensity x-ray for their research. In addition, new modeling approach and software development permit valuable connection between theoretical and experimental analysis. Â Characterization with neutron and x-ray scattering has made significant contribution to the large research activities in engineering, materials development, polymer dynamics, chemical technology, biological studies, and physics, and will continue to do so.Â
The objective of this conference is to bring together scientists who develop neutron and x-ray scattering instruments, perform characterization experiments, synthesized materials and computation. Discussion will be focused on recent results and ideas in these areas. The conference will consist of lectures and poster on new and emerging areas in scattering technique
